Fig. 8 is a sectional side elevation on line 8--8 in Fig. 1.

Fig. 9 is an elevation of a cocoon basket which is an accessory of thereeling pan,

Fig. 10 shows a plan of the said basket.

As will be seen from the drawings; in the rear portion of the reelingpan I, a water tank 2 for reeling purposes, is provided; the tank bottomslopes down from both sides towards the middle as shown at a and binFigs. 3 to 8. The partition walls 3 of thetank, form adjusted cocoonstorage portions 4 and 5 with curved walls and in the walls 3 of thecurved portions 4 and 5, several projections 6 are provided for hangingfibres.

On the right hand side of the curved portion 4, a hollow pot I isformed, for use of fibre end catching and in the interior of the pot, asuitable heating arrangement such as steam injection pipe is provided.

The boundary wall of the pot I is slightly projected up all around as at8; and to the projections 8, bent strips II] of a cocoon basket 9 areadapted to hang.

As shown in Figs. 9 and 10 the cocoon basket 9 is fitted with handlepieces II and at suitable points of the bottom and side walls, severalholes I2 are bored.

On the left hand side of curved portion 4, a fibre adjusting hollow potI3 is formed and the top portion of the wall I4 of the pot I3, is madeso as to be able to suspend cocoon basket I I.

The bottom of fibre adjusting pot I3 is connected to the bottom of thefibre catching pot I by means of connection pipes I5; and in the middleportion of the pipes, a Water tank I6 is provided, so as to be able toautomatically regulate the water levels of fibre adjusting and fibrecatching pots. The bottom of the hollow pot I3 5 is also connected tothe bottom of the water tank 2 by means of conduit I'I.

On the right hand side of the curved portion 5, a basin I8 for droppedcocoons, is provided and at the bottom of the basin I8, a drainage holeI9 10 is bored.

On the left hand side of the curved portion 5,

r a storage basin 2%] for boiled cocoons is provided and at the bottomof the basin, a drainage hole 2'I is bored.

As shown in Fig. land Fig. 2", the basin for boiled cocoons 20 and thebasin for dropped cocoons are formed in one body, being surrounded by awall 22.

From boiled cocoon basin 2!], the bottom surface gradually slopes uptowards the dropped cocoon storage, as shown at 23, thus making itconvenient for picking up boiled cocoons and for general reelingoperation.

On one side of the boiled cocoon basin 20, an25 inferior cocoon storagebasin 24, a Wastes storage basin 25 and a chrysalis storage 26 areprovided, side by side and in the bottom portions of these storagebasins, drainage holes 21 are bored.

To explain the operation: Boiled cocoons are' first taken to the storagebasin 20 by using cocoon catchers; then utilizing the inclined plane 23of the boiled cocoon storage, a suitable number of adjusted cocoons, isretained at projections 6.

The cocoons retained at the hollow curved por- 35 tions 4 and 5 by theprojections 6, are fed to the cocoon fibre feeding apparatus as much asnecessary. Cocoons not adjusted at the boiled cocoon storage, arebrought to the cocoon basket 9 suspended in the fibre catching portion 1and 40 then boiled.

Cocoons properly boiled there, are brought in the basket to the fibreadjusting pot I3.

Then cocoons arranged or adjusted there are suspended from theprojections 6.

Cocoons retained in the hollow portions 4 and 5 of water tank 2, arekept at the same temperature as the cocoons which are being reeled andgradually fed.

Cocoons, drop fibred in the water basin 2 and 50 chrysalis graduallyslip down to the lowest portion of inclined faces a and b.

Chrysalises are taken to the chrysalis storage basin 26 and droppedcocoons are taken to their storage basins I8. When they have fairly col-55 lected, they are taken over to the fibre catching pot 1 and used foroperation.

These dropped cocoons placed in tank 2 which have fibre ends, aredirectly taken to the fibre feeding apparatus and used for reelingoperation.

The present invention has the construction as explained above and it isevident that it is convenient to take up dropped cocoons and chrysalis.

Again cocoons to be fed to the fibre feeding apparatus, are kept inwater of proper and constant temperature and therefore the quality ofthreads produced can be maintained uniformly. Cocoons, drop fibred ornot fibred are boiled in fibre catching pot 1 and therefore it isconvenient for catching fibre ends; moreover as they properly cool infibre adjusting pot, they are prevented from being excessively expanded,thus making the fibre separation easy.

The catching pot and the fibre adjusting pot are connected together bythe connection pipes I5 fitted with water tank l6 at their middleportion, so that the water levels of these pots are kept uniform andconstant, regardless of existence of cocoon basket; both hot and coldwater do not flood over; and it is not necessary to supply water.

Therefore density of hot Water in the fibre catching pot, is keptuniform and by the provision of water tank, hot water in the catchingpot and cold water in the adjusting pot, Will not mix. Again the bottomportions of the fibre adjusting pot and the water tank, are connectedtogether and the temperatures of water can be kept about the same; andby the water supply from water.

pipe provided in the upper portion of reeling tank, the water levels ofthe thread reeling water tank, the fibre adjusting portion and the fibreend catching portion -may be kept constant and prevented from beingflooded.

Thus, according to the invention in the reeling operation, it isconvenient and the eficiency is increased and therefore superiorproducts may be obtained.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States of America is:

1. A reeling pan for multispool reeling machines comprising arectangular pan, a water tank for thread reeling at one side of said panand fibre end catching and fibre adjusting pots together with droppedcocoon storage, boiled cocoon storage and waste storage basins at theopposite side of said pan, and a partition located in said pan andprojections on said partition for hanging fibres thereon.

2. A reeling pan for multispool reeling machines comprising arectangular pan, a water tank for thread reeling at one side of said panand fibre end catching and fibre adjusting pots together with droppedcocoon storage, boiled cocoon storage and waste storage basins at theopposite side of said pan, and a heating device arranged in the fibreend catching pot, the edges of the last mentioned pot projectingupwardly above the bottom of said pan.
